only of number and fituation^ without regard to 

 the offices of the parts in framing the terms. 

 Ludwig^ of Leipfic^ who has endeavoured to com- 

 bine the fyftems of Rivinus and Linn^us, by 

 taking his dajfes from the method of the former, 

 and his orders from that of the latter, has avoided 

 this mode of expreffion, in fubftituting the terms 

 monanthera^ monoJiyU^ &c. &c. 



The author begins the new and enlarged edition 

 of the Syftema Vegetahilium of 1767, by premifing 

 a compendious view of the philofophy of vege- 

 tation, and then proceeds to what he calls Delineatio 

 Plant^^ fomething analogous to what he had en- 

 titled, in the editions prior to the loth, Methodus 

 Demonjirandi Vegetahilia. Here he introduces all 

 the terms he makes ufe of in defcribing plants, 

 and, by a methodical and apt difpofition of them, 

 really explains them at the fame time. After this, 

 he gives the Clavis et Chara5ieres ClaJJium^ and then 

 comes to the fyilem itfelf. 



The prerogative of any artificial fydem in 

 botany, is fuppofed to confift in its keeping toge- 

 ther, as much as poffible, the genera^ in what are 

 called the natural dajfes or orders, and thus fo far 

 approaching to the fyftem of nature. All artifidal 

 fyftems being founded on forne^ or other^ or all 

 the parts of fru^ifica^on^ without regard to habit, 

 will be found in many inftances to break the order 

 of the natural ciaiTes, and disjoin genera^ which 

 nature feems to have claiTed. The more fimple 

 and uniform the clafTical charadiers of any fyftem 

 arc, the more they are likely to interfere in this 

 refpedj neverthekfs, it is plealing to obferve, how
